Culvert and sewer deterioration and repair using polymer liners
Dr Ian Moore
One Day Workshop
Central to the maintenance of human health is the supply of safe drinking water and the disposal of wastewater. Much of our water supply and water removal infrastructure is now in poor condition, and civil engineers and the society they serve face an increasing challenge to maintain these basic services. Aging infrastructure can however be renewed using lining techniques that minimize the disruption associated with trench excavation and buried pipe replacement. The course instructor builds on established practice and his research studies over the last two decades. The important limit states for these systems are explained, methods of estimating liner response to external loads are outlined, and liner installation and design procedures are explained.
The course is designed for private and public consultants, specialist contractors, and graduate students. Enrolment in this workshop format is limited to 24. The course examines both structural and geotechnical issues. Specific topics covered during the course are:
- Culvert and sewer deterioration
- Liner systems and processes
- Structural performance criteria
- Design to resist external fluid pressure
- Design considering the effect of imperfections on liner stability
- Earth loads on ‘old’ pipe
- Design for earth loads on the liner
